The FDA only requires companies to list out protein, fat, fiber and moisture, so it can be difficult to find out the percentage of carbs that it contains.
We recommend Orijen,
which has an estimated 23% carbs (peas, chickpeas, red and green lentils, navy and pinto beans, alfalfa).
Notably, it contains chicory which is high in inulin; this is a compound that is a great source of fiber and is also a prebiotic which promotes good bacteria in the GI tract, which can greatly aid in proper digestion. (note, probiotics introduce 'good bacteria' and prebiotics nourish the good bacteria that is already there).
The 23% carbs are a low amount that will not only reduce flatulence, but also leaves plenty of room for ingredients that you do want: 36% protein (turkey, chicken, flounder, mackerel, whole eggs) and healthy fats.
The 36% is well above average protein levels when compared to all other commercial foods.
